OK im alittle freaked out right now, i had been taking Posiedon for awhile now and never really got a full blown flush. I just got back from working out and mixed 1 scoop of poseidon in 8 oz of water with 2 scoops of. About 10 minutes after i drank it my face started to feel hot and weird. I took off my sweater and i have bright red patches on my arm, my neck and on my back... My entire body isnt red just these patches and my face is hot Is this the niacine flush or do i got some sort of weird rash.. The red patches are itchy.
